BACKGROUND OF THE INVENTION 1. Field of the Invention The field of artto which this invention pertains is found generally in the class ofSurgery and more particularly in the subclass of douches and even moreparticularly in the subclass of vaginal douches.

2. Description of the Prior Art Vaginal douche devices, and syringes ingeneral, are well known in the art and commerce and are exemplified bymany patents both United States and foreign. In particular, severalpatents represent attempts to provide a syringe which may be folded,rolled or disassembled to form a small assemblage for packaging andtransport. Many of these syringes are intended for a one-time use, thenfor discarding of the apparatus. However, these various syringes havenot proved commerically acceptable for many reasons, among which are:the syringe is too complicated to assemble and use; the syringe does notprovide means for increasing or decreasing the pressure by manualcontrol by the user; and the syringe does not lend itself to the use ofmodern materials for the best sanitary presentation for use by the user.It is contemplated that the apparatus of this invention may be readilysterilized and that when the package is opened for use that it may bereadily filled, assembled and provide manipulative control by the user.

The particular prior art which relates to the present invention is bestrepresented in US. Pat. No. 2,925,084 to Brewer of Feb. 16, 1960 and inUS. Pat. No. 3,144,866 to Ellis of Aug. 18, 1964. In the device ofBrewer there is no provision, except for gravity, of any regulation ofthe pressure of the fluid from the nozzle. 1n Ellis the preassembly ofthe filler plug to the bag and the locking of the nozzle to the plug israther a complicated process.

The simple packaging arrangement and ease of assembly of the syringe ofthis invention as well as its simple inexpensive construction, representa significant contribution to the art.

The disposable apparatus as exemplified in the drawing and in thedescription which follows includes a nozzle portion, either unitary orformed in sections, which is preferably formed by present moldingtechniques to provide an inexpensive and aesthetically acceptable andmedically proved inserting member. This nozzle is shaped at itsconnecting end so as to be readily assembled in a fluid-tight manner toa forward end closure or cap member. This cap is formed so as to engageand retain a collar, which collar is disposed to slidably receive aflexible bag within which the fluid forming the bulk portion of thedouche application is poured. In the specification and drawing there areshown a number of exemplifications of means for attaching thenozzle tothe cap portion. Each of these methods is representative of the assemblyease contemplated for this apparatus.

The flexible bag is preferably a cylindrically shaped tubular memberhaving an open and closed end. The open end is mounted on or slidable ona collar or sleeve having an expanded diameter portion. The cap and thecollar are constructed and sized to retain the bag therebetween. Theengagement of the cap to the collar may be by a snap rim or by a threador wedge fit.

It is an object of this invention to provide a disposable douche syringein which the several members may be arrayed in a disassembled conditionfor packaging in a minimal space box or bag, said syringe disposed forready assembly and use by the user.

It is a further object of this invention to provide a disposable douchesyringe in which a nozzle is attached to an end closure or cap member.The syringe includes a flexible bag of generally tubular constructionhaving one end closed and the other end sized to be slidable on theouter surface of a collar member, the bag and collar member being thenan assembly mountable in the retaining rim of the cap member.

INTENT OF THE DISCLOSURE Although the following disclosure offered forpublic dissemination is detailed to insure adequacy and aid in theunderstanding of the invention, this is not intended to prejudice thatpurpose of a patent which is to cover each new inventive concept thereinno matter how it may later be disguised by variations in form oradditions of further improvements. The claims at the end hereof areintended as the chief aid toward this purpose, as it is these that meetthe requirements of pointing out the parts, improvements andcombinations in which the inventive concepts are found.

There has been chosen a specific embodiment of the disposable douchesyringe and modifications of the nozzle and cap member as adapted foruse therewith. This specific embodiment and the alternate embodimentsthereof have been chosen for the purposes of illustration anddescription as shown in the accompanying drawings wherein:

DESCRIPTION OF A FIRST EMBODIMENT In the following description and inthe claims various details will be identified by specific names forconvenience. The names, however, are intended to be generic in theirapplication. Corresponding reference characters refer to like membersthroughout the several figures of the drawings.

The drawings accompanying, and forming part of, this specificationdisclose certain details of construction for the purpose of explanationof the broader aspects of the invention, but it should be understoodthat structural details may be modified in various respects withoutdeparture from the concept and principles of the invention and that theinvention may be incorporated in other structural forms than shown. Inparticular in FIGS. 1 and 2, there is shown a one-piece nozzle which isremovably mountable into a cap or end closure member 12 which isdisposed to engage and retain a flexible bag 14 in a fluid-tightcondition as it, the bag, is gripped between the cap and a collar orsleeve member 16.

In particular, it is to be noted that the nozzle 10 is preferably moldedof plastic such as polypropylene, polyethylene and the like. The nozzleis formed with a hollow portion which extends from an inner open end 22to a discharge closed end 24. Positioned near end 24 and extending fromthe interior 20 to the outside of the nozzle are a plurality of ports25. These ports provide means for directing and carrying the flow offluid from the nozzle during the time of use. This nozzle is ofconventional construction and configuration to conform to acceptablemedical practice and use. As shown in the drawing, the nozzle iscontemplated to be a generally full size representation of a preferredconfiguration. It is to be noted that the nozzle shown in FIGS. 1 and 2includes a shoulder portion 26 which is adapted to engage a gasket 28 ofrubber and the like and having a sufficient resiliency to act as a fluidsealing means when this shouldered end of the nozzle is inserted intothe cap 12. As particularly seen in FIG. 2, the entering end 22 of thenozzle includes a reduced portion 30 which extends from shoulder 26 to aslightly larger tapered collar portion 32.

Referring now in particular to the cap 12, it is to be noted that thecenter portion of the cap has a collar retaining sleeve portion 36. Thebore of the sleeve portion is tapered to accept the end 32 of thenozzle. The rightward end of the bore is sized to pass the largest partof the collar 32 while the leftward end of the bore is sized to snuglyengage reduced portion 30. This retaining sleeve has relieving slots 38formed in the left portion thereof and an outward shoulder engagingportion 40 which is spaced and shaped so as to engage the inner end ofthe collar portion 32 when the nozzle is inserted in the cap 12. Theouter portion of the cap 12 has a tubular extending portion or flange 41terminat ing with an inwardly extending lip 42 which is disposed toengage an annular outwardly extending portion 44 formed in the collarmember 16. The cap is preferably made of a plastic material which issufficiently rigid to retain the tapered collar 32 and annular portion44. The material is also sufficiently flexible to snap over the annularportion 44 or as spring finger members of the sleeve 36 are deflectableto pass the collar 32 and to then spring into retaining engagement withthe inner shoulder of the tapered collar 32. Also, for ease ofmanipulation with respect to the member 16, the axial extent of thetelescoped part of the flange 41 is in the order of one half, or less,of the axial extent of member 16.

The bag 14 is preferably made of a thin plastic film which may bepolypropylene and the like and is preferably two or three thousandths ofan inch in thickness. The bag is tubular in construction and sealed atthe back end 50 and is sized so that its open end 52 is disposed toslide over the annular portion 44 of the collar 16.

Assembly and Use of the Disposable Douche Syringe of Figs. 1 and 2 It iscontemplated that the nozzle 10, cap 12, bag 14 and gasket 28 will bepackaged in a carton or envelope so that these items may be shipped andstored as unassembled individual syringes. As an assemblable syringethese components, at the time of packaging, are sterilized so that afterpurchase the user may open the package and have a douche syringehygienically ready for assembly and use. As contemplated, the bag 14 maybe folded flat or may be accordion pleated for packaging and storage ina minimum of space. The bag may be rolled if desired, and in certaincircumstances may be used as the package means for the other memberscomprising the syringe assembly. It is only necessary that at the timeof assembly the bag be opened so that end 52 may be slid over the leftportion of the collar 16 and forwardly over the annular ring portion 44.It is, of course, to be noted that the bag 14 may now be filled with thedesired amount of water or a solution of water and a medicant or thelike as determined by the preference of the user and/or the manufacturerof the device. After the filling of the bag 14 and with the end of thebag 141 forwardly of the annular portion 44 of the collar member 16, thecollar and bag are brought to the lip 42 of cap 12 which is then snappedinto the position of FIG. 1. As thus assembled, the bag 14 is retainedin a fluid-tight condition, after which the nozzle 10 is then brought inway of the interior portion 36 of the cap and with the rubber gasket 28in place adjacent the collar portion 26. The nozzle 10 is now pushedinto the cap 12 until it assumes the position of FIG. 1 whereat the lipportion 40 has engaged the rear shoulder of the tapered portion 32 tocam the nozzle 10 into a fluid-tight condition. This assembled andfilled, the syringe is ready for use. The syringe is used in thecustomary manner and after the fluid in the bag 14 has been expelled bygrasping and squeezing of the bag by the user or by an attendant, thesyringe is discarded. If desired, the cap 12 is removed from the collar16 and the nozzle 10 may be removed from the cap 12 so that the contentsmay be wrapped in the bag and discarded. On occasion, only the bag 14 isdiscarded. At a later time, a new bag 14 may be placed upon collar 16and the syringe filled and reassembled for use.

In general, it should be noted that in FIG. 1, as for the other forms tobe described, the bore diameter of sleeve or collar member 16 issufiiciently generous to readily admit the collapsed bag 14 and one ortwo fingers, so that finger pressure in the course of stuffing an almostdepleted bag 14 into member 16 may force the dispensing of substantiallyall the liquid contents of bag 14; in practice, a sleeve bore of 1.75inches diameter and 2.0 inches length has been found to be highlysatisfactory.

DESCRIPTION OF THE EMBODIMENT OF FIG. 3

Referring next to FIG. 3, a nozzle 50, which is similar to nozzle 10,has its inner end threaded at 52 so as to engage a threaded portion 54in an end cap 58 which is similar in construction to the cap 12. Cap 58has an inner lip 42 which is sized to engage the collar member 16 in themanner of the syringe of FIGS. 1 and 2. The bag 14 and collar 16 areassembled as above described and are fastened to cap 58. The nozzle 50has its threaded end 52 provided with the rubber gasket 28 mountedthereon and then is brought in way of the threaded opening 54, whereuponthe nozzle is rotated to threadedly engage and seat in the opening 54.After assembly, the syringe is used in the manner of the syringe of FIG.1 above.

DESCRIPTION OF THE EMBODIMENT OF FIG. 4

Referring to FIG. 4, it is to be noted that a nozzle 70, similar tonozzle 10, has a tapered end 72 formed to mate in a tapered socket 74formed in a cap 76. A nozzle and cap assembly as thus formed isfluid-tight without a gasket 28 as is shown in FIGS. 2 and 3. Thetapered end 72 is caused to enter the socket 74 and engages and seats ina frictional and sealing engagement to provide a fluid-tight retentionof the nozzle 70. The cap 76 is assembled to bag 14 and collar member 16in the manner above described, after which the syringe is used in themanner of FIG. 1 above.

It is to be noted that in certain assemblies it may be desirable thatbag 14 be attached to collar member 16 prior to packaging for shipment.When such is the case, the bag may be attached as by heat-sealing orcement. It is also noted that the cap and nozzle may be molded as asingle unit where desired.

Although the lip 42 is preferably sized and shaped so as to be snappedonto the annular portion 44, it is also contemplated that the lip andportion may be formed as compatible threads for assembly by rotating. Itis further noted that the collar portion 36, threaded portion 54 andtapered socket 74 can be formed on the cap so as to extend outwardly ofthe face of the cap as the syringe is assembled for use.

DESCRIPTION OF THE EMBODIMENT OF FIGS. 5 and 6 In the arrangement ofFIG. 5 and 6, the collar or sleeve member 80 is slightly enlarged at aforward land 81 having integral threads 82 for removable engagement tothe threaded bore of the flange 83 of cap member 84. A seal washer orgasket 87 of yi eldable plastic or elastomeric material may be retainedin cap 84, in radially overlapping register with the adjacent axial endof sleeve 80. Preferably, the thread arrangement of members 80-84 ischaracterized by a multiple pitch, and the angular extent of each ofthreads 82 is such as to preclude their angular overlap; thus, for thethreelead pitch shown, each thread 82 is at least no greater than 120 inangular extent, and the three threads 82 are equally spaced (oninterlaced helices), so that the cap 84 and sleeve 80 can be securedwith substantially less than 120 of engaged relative rotation.Manipulation is further aided by spaced peripheral ribs 8586 onexternally exposed parts of sleeve 80 and flange 83, and byproportioning these parts so that the axial extent of sleeve 80 is inthe order of at least twice the axial extent of the telescoped part offlange 83, when assembled.

Nozzle assembly may be as described for FIG. 3, and so the samereference numbers are adopted, with primed notation.

In use, the open end of the flexible bag 14 is first drawn through thebore of sleeve member 80, and then folded back over the threaded land 81and into substantial overlap with the ribbed exterior of sleeve 80, asshown; such subassembly enables a firm grasp of the bag end againstsleeve while loading the same with syringe liquid, and while latermanipulating the loaded bag and sleeve into threaded engagement with capmember 84. Alternatively, FIG. 6 illustrates that by providing thenozzle bore 54' of relatively large diameter (to accommodate a largernozzle base 50' the cap 84 may be assembled to the bag-fitted sleeve 80prior to filling with liquid, the bore 54' being large enough toaccommodate splash-free faucet filling prior to nozzle attachment at 52-54.

DESCRIPTION OF THE EMBODIMENT OF FIG. 7

Referring to FIG. 7, collar or sleeve is shown to have external threads91 at one end, and cap 92 has coacting threads 93 on the inner surfaceof its peripheral flange. A pressure-sensitive adhesive band 94,continuously lines a region of sleeve 90. Bag 14 may be placed aroundthe collar 77 so that it is gripped and held in a fluid-tight mannerbetween collar 77 and cap 78 by the engaging action of threads 91-93;bag 14 is shown to have its mouth portion placed first around thecircumference of the collar 77 and then folded back within its bore,being retained by adhesive contact at 94. This placing of the bag can,however, be reversed by placing the mouth portion of the bag 14 first inthe bore of collar 77 and then folded back as in FIGS. 5 and 6, beingagain temporarily retained by adhesive contact at 94.

DESCRIPTION OF THE EMBODIMENTS OF FIGS. 8 to 10 Referring to FIG. 8, asleeve or collar member 95 is externally characterized by a conical ramp96, terminating in a circumferential groove 97 near the end to beengaged by cap 98 (FIGS. 9 and 10). The bag 14 may be rolled over orsecured to a rubber band 14' of sufficient resiliency, an O-ring or agarter ring. When the mouth portion of the bag 14, containing one of theabove elements rubber band, O-ring or garter ring or the like is broughtinto register with groove 97, the bag will be self-retained insubassembly to the sleeve 95, for convenience in filling and inmanipulation for assembly to cap 98. Cap 98 is shown with an axiallyextending lip or flange 99 having a bore which exceeds the minimumdiameter of groove 97 to define a clearance C, the latter being greaterthan the bag thickness but less than the thickness of the rolled end,rubber band or the like 14'. An outwardly flared mouth or counterbore99' serves to engage over and inwardly cam the end 14' as the cap istelescoped over the preassembled bag and collar, thus compressing end14' to an elongated section, as suggested in FIG. 10. Upon fulltelescoping, the bag is secured and sealed in the relation depicted inFIG. 10, and the syringe is ready for use upon assembly of the nozzle,as previously described.

GENERAL REMARKS The material from which some of the embodiments aremanufactured has not been specifically recited. The

same material can be used throughout for the various embodiments.Generally speaking, nozzle, cap and col lar parts are relatively stiff,and the bag is soft and pliable, and the polyethylenes andpolypropylenes are satisfactory basic materials.

The disposable syringe is illustrated as having a nozzle for femininehygiene. It is believed that this will be one of the main uses for thedisposable syringe. The disposable syringe can, however, be used forother purposes as well, and the plurality of openings 25 can be replacedby a single aperture placed, for example, at the tip of the nozzle. Thetip of the nozzle is illustrated as somewhat bulbous. The nozzle can,however, be tapered outwardly so that the tip has the smallest diameter.

Also, it has been indicated that the sleeve member (16, 80, etc.,) ispreferably of at least a certain length relation to the overlap with thecap that manual manipulation and assembly are facilitated. By the sametoken, it will be understood that the length and bore diameter of thesleeve may be such as to accommodate or substantially contain bag andnozzle elements, in certain packaging of the disassembled parts.

The terms inner, outer," right, left and the like as used in the abovedescription pertain to the as sembly of the disposable syringe as shownin the drawings and do not necessarily pertain to the position orattitude in which the disposable syringe may be used and assembled.
